Re: pic: 1726 NURC robot prototype
Oh wow that design looks really interesting!
I'm glad you guys finally got signed up. I can't wait till competition day to see how your design works |

Re: pic: 1726 NURC robot prototype
Fantastic guys! Keep it up. We are building our new one this year. Here is the team website with some picts so far
http://falconrobotics.design.officel.../pictures.aspx We have two full sets of prop to build!! We have a lot of work to do. We also want you guys to be involved in the design of the next APASE competition. We will talk more later! |

Re: pic: 1726 NURC robot prototype
Thank you, thats very interesting, I might have to get me one of those so I don't have to worry about the micro controller all the time. And the size is another advantage for applications like these.

Re: pic: 1726 NURC robot prototype
The vex signal splitter is a neat thing, we're using it with 3 Banebots speed controllers to drive the T500 bilge pump motors. The batteries are two Vex 7.2v 2000mAH wired in series to provide nominal 14.4v. The splitter takes power from the speed controller's Battery Eliminator Circuit.
We looked at the signal on the tether output port on the transmitter using an oscilloscope, and it's a nice 6 channel PWM signal, on the red and green wires in the 4 conductor connecting cable. I wonder if we can do some more compacting work to be able to fit more stuff in the robot...it's getting crowded in there! Wires take up a lot of room. |

Re: pic: 1726 NURC robot prototype
That's an experiment that still needs to be done! I think Gary sees the need to do the experimenting, so maybe it will get done soon...
As for the signal splitter channels, it uses the 4 joystick axes to control the first 4 outputs, and the buttons for the last two. IFI suggests not using the last two channels with servos, as they seem to have some jitter at the neutral position. Last edited by MrForbes : 27-04-2008 at 18:37. |

Re: pic: 1726 NURC robot prototype
How stable is it underwater? What keeps it in it up-right position?
Have you named it yet? |

Re: pic: 1726 NURC robot prototype
a few pounds of steel stakes keep it upright (they are tie wrapped on the bottom skids).
I don't think they've come up with a real name yet, but I'm sure it will be highly technical when they do! |
